DROP-SPOUT FOR CANS.

SPECIFICATION forming part of Letters Patent No. 430,820, dated J' une 24, 1890.

Application filed March 21, 1890. Serial No. 344,714. (No model.)

To all whom it' may concern.-

Be it known that I, GEORGE W. BANKER, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Drop-Spouts for Cans, of which the following is a specification. l

My invention relates to improvements in drop-spouts, so called, for cans adapted to contain liquids; and it consists, first, in improvements in thespout for the can, and, second, in improved means whereby the spout when projected may be rigidly held.

vIn the drawings the same reference-letters indicate the same parts in all the figures.

Figure l illustrates a vert-ical section of my improved spout as attached to a can. The can being partly broken away, the spout is shown in its depressed position. Fig. 2 illustrates a view of the parts shown in Fig. l, the spout, however, being in its projected position and the cock turned to allow the liquid to flow out. Fig. 3 illustrates a view of the same, as shown in Figs. l and 2, of an alternative construction ot' my improved device, showing a special cap for covering the spout.` Fig. l illustrates in sections the several parts constituting the cap shown in Fig: 3. Fig. 5 illustrates a plan view of the plug for the stopcock invented by me. Fig. 6 illustrates a vertical sectional View of the plug shown in Fig. 5. Fig. 7 illustrates an under view of the plug shown in Figs. 5 and G, looking at it from its larger end.

A is the can. B is the top thereof. f

VC is a dish-shaped piece of tin, having a iiange D at its `periphery adapted to fit into the groove E, ordinarily made around the opening in cans of the kind under contemplation.

F is a downwardly extending packingholder made on or attached to the under side of the dish-piece O. 1 It has vertical openings G G through it, the diameters of which are such as to exactly coincide with the diameter of the tapering spout-tube H at its lower and larger part. Y

I is a packing, preferably of cork, although other material may be used, which is placed in thc packing-holder F, and which I prefer to make of such size that it will project inwardly somewhat beyond the edges of the openings G G in the paclingliolder. so that when the tapering spout is drawn outwardly it will compress the packing somewhat` thus securing a tight joint between the spout and the packing.

J is the tubular cross-piece, which terminates the spout, within which is placed the tubular plug K, which has the usual orifice L, flange M, and cross-bar N. These parts do not require special consideration here.

O is the covering-plate for the dish O, preferably made ot taggers tin or other suitable material. It is of course sealed air-tight, by solder or otherwise, at its edges, as usual.

The operation of the device is as follows: During transportation or storage the parts remain as shown in Fig.`l. Then Ait is desired towithdraw the liquid from the can, a knife or other suitable implement is employed, whereby the central portion of the cover O is removed. The upper end of the spout, which constitutes the stop-cock, at this time resting in the dish C, is then grasped in any conven ient manner and pulled outwardly. This act, by reason of the tapering form of the spouttube, which form I prefer-, compresses the packing I, and by the time the spout has been pulled outwardly nearly as far as it will go its lowermost part, which has the greatest diameter, engages with the sides of the openings G G made in the packing-holder. rlhus the entire withdrawal of the spout will be impossible, and it also is supported firmly in its projecting position, the packing' in the meantime having been considerably compressed, thus sealing the joint. The stop-cock may now be turned and the liquid will flow until it be turned off again.- By this means it is not necessary to tip the can when desiring to stop the flow of the liquid, and the spout may be left permanently in its projected position, and the can, which is 'frequently a large heavy one, may be left permanently upon its side. This is a very material improvement in these devices, because spilling of the liquid was practically inevitable under the old form of spout, consequent upon tip ping the can backward and forward during use.

IOO

In Figs. 3 and 4 I show an improved cap for covering the spout,which in soineinstances I prefer rather than that shown in Figs. l and 2. The dish -piece C, the packing-receiver F, the spout and its stop-cock, and the can are made the same as shown in Figs. l and 2, with the exception that it is not necessary to make the dish C so deep; but over the dish I form a taggers tin or equivalent cap P, (see Fig. 4,) which is substantially the diameter of the dish-piece C, and in its central `part I form an upwardly-eXtending chamber Q. This taggers-tin cap-like piece is adapted to iit within another cap R, made, preferably, of stiffer metal, which is of about the same diameter as the dish-piece C and taggers-tin l piece R. Ithas an upwardly-extending chamber S, the annular vertical walls whereof are threaded exteriorly, and it has an opening T through its upper side. U is a cap or cover having threads upon its edges adapted to screw down upon the cap-piece R. It has also a sealing-piece V, of cork, linoleum, or equi valent material, placed in its upper part, adapted to seal the joint between the edges of the cap R and itself when screwed down firmly into position. The operation of thisimprovement is obvious. The screw-cap U bein unscrewed, a knife or equivalent implement is inserted through the opening T in the-cappiece R, whereby the taggerstin cap P may be cut away and the spout then withdrawn and manipulated as before.

In Figs. 5, 6, `and 7 I show an improved plug for the stop-cock, which I am able to make at very slight expense, since it can be constructed by what is known as the automatic soldering operation. The plug-tube is shown at d. It is substantially the same as that shown in .the other figures; but the cross-bar b at its end, instead of being a straight bar, as shown at N in Figs. l, 2, and 3, is a little piece of metal swaged up so as have a partial saucer shape, with lateral projections c c opposite each other. There is also a concavity d made in the center of its under side. The rounded part of this little piece of metal, (shown at E, Fig. 7,) is made of such size as approximately to fit the larger end of the plug a. I am thus enabled to place each plug within its own saucer-shaped cross-piece, and by dropping a small piece of solder into the plug, all the parts together being carried vover a heated surface, the solder will be melted and it will Iiow down into the joint between the plug and the saucer b, by reason of the concavity d made in the saucer, thus materially reducing the expense of this part of the device.

It will be obvious to those familiar with this art that modifications may be lnade in the details of construction of my invention and still its essential features be present. I therefore do not limit myself to the details as specifically shown and described.

It will be observed that by my invention I accomplish the following valuable results: lleretofore spouts or faucets provided with stop-cocks have been rigidly attached to the upper surface of such eans,which project upwardly therefrom about. an inch. This of course requires the wooden packing-case for the can to be at least an inch higherthanthe can proper would require, thus adding not only the expense of the case, but also materially increasing the freight charges because of the greater bulk of the packing-cases. By

in Figs. l and 2, there is no project-ion whatever by the spout or its faucet above the top of the can proper. I therefore secure the savings above referred to.

I claiml. The combination of a movable spout, a stop-cock on one end thereof, a stationary packing adapted to engage with the spout when projected, a holder for the packing, through which the spout passes. and by which it is supported at both sides of the packing when projected, substantially as set forth..

2. The combination of a tapering spout, a stop-cock on one end of the spout, a packing adapted to engage with the spout, a casing for the packing through which the spout passes, and by which it is supported at both sides of the packing when projected, the packing projected toward the spout beyond the openings in the casing, substantially asset forth.

3. The combination, with a drop-spout for cans, .of a stop-cock upon the 4outer end of the spout, a dish-shaped piece, within which it rests when retracted, a superposed taggers-tin cap, Valso a threaded cap having an opening through its bottom, and a screwcover adapted to be screwed upon the lastmentioned cap, substantially as set forth.
